An attorney for an upstate New York man accused of fatally shooting a 20-year-old woman who was with a group of friends who accidentally turned into his backcountry driveway called it a “terrible accident” involving a defective gun as arguments in his murder trial began. Kevin Monahan is charged with second-degree murder in the death of Kaylin Gillis, who was out with friends who got lost while heading to another person’s house on a Saturday night last April. The group’s two cars and a motorcycle mistakenly turned into Monahan’s driveway near the Vermont border.
